asp.net mvc - passing query string after the controller name in mvc -

i trying pass parameter in mvc after controller name

i added

routes.maproute(      name: "product",       url: "product/{*id}",      defaults: new { controller = "product", action = "index", id = urlparameter.optional }             ); 

this did not work

i tried url: "product/{id}",

but if remove lines above it(the lines below in post), working

routes.maproute(                 name: "default",                 url: "{controller}/{action}/{id}",         defaults: new { controller = "home", action = "index", id = urlparameter.optional }             ); 

order in register routes matter. first route matches request used. if understand correctly, had:

routes.maproute(     name: "default", ...  routes.maproute(     name: "product", 

default route generic, , since registered first picked time of requests, shadowing product route.

correct way registed routes start specific ones, , have generic registered @ end. in case should reversed:

routes.maproute(     name: "product", ... routes.maproute(     name: "default",
